Perpetual Bedhead
I haven't owned a blowdryer or any hair styling tools in 20 years. I air dry my hair and apply a bit of conditioner when it's still wet. Let's face it, when you're in your forties your hair is no longer youthful but you can give it shine and style again.
I am also bedbound 22/24 hours a day, and swimming + PT 3 x a week wrecks my hair. So last week I ordered six bright pink curling devices from ASOS, and use 4 when my hair is half way dry. My hair is out of my face, and the rollers are soft enough so I can on my side.
Added benefit: my hair now looks soft and nice, making me feel desirable and happy. You can have long hair in your forties but you may need to experiment with a simplified hair regimen, 5 minutes tops. Most importantly, find out what makes you and your hair happy!
